Adding analog input (NI)

[amh]

Code: Select all

1. Create session and add input

d = daq('ni');  % create ni session
ch = addinput(d,deviceID,channelID,measurementType)  %add ni analog input

Measurement Type:



2. Set acquisition rate

Code: Select all

d.Rate = 10 % acqusition rate;

3. Set channel configuration

Code: Select all

ch.ADCTimingMode = "HighSpeed"  %  allow higher acquisition rate
ch.BridgeMode = "Full"  %  set bridge mode to Full
ch.NominalBridgeResistance = 350 % set  nominal bridge resistance
ch.ExcitationVoltage = 10; %set excitation voltage

Code: Select all

ch.Sensitivity = 100; % sensitivity in V/g or V/m/s^2

3. Acquired data at specific duration

Code: Select all

data = read(dq, seconds(1));
